Detailsinfo

A vulnerability classified as critical has been found in moonlight-stream moonlight-common-c (version unknown). Affected is an unknown function of the component GameStream Client. The manipulation with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Moonlight-common-c contains the core GameStream client code shared between Moonlight clients. Moonlight-common-c is vulnerable to buffer overflow starting in commit 50c0a51b10ecc5b3415ea78c21d96d679e2288f9 due to unmitigated usage of unsafe C functions and improper bounds checking. A malicious game streaming server could exploit a buffer overflow vulnerability to crash a moonlight client, or achieve remote code execution (RCE) on the client (with insufficient exploit mitigations or if mitigations can be bypassed). The bug was addressed in commit 02b7742f4d19631024bd766bd2bb76715780004e.

The weakness was shared 12/14/2023 as GHSA-r8cf-45f4-vf8m. The advisory is available at github.com. This vulnerability is traded as CVE-2023-42799 since 09/14/2023. The technical details are unknown and an exploit is not available.

Applying the patch 02b7742f4d19631024bd766bd2bb76715780004e is able to eliminate this problem. The bugfix is ready for download at github.com.
